What is Diegetic and Non-Diegetic Sound? Complete Beginner's Guide

What is diegetic sound definition

Diegetic audio is a sound that is created in the world of a story, or the diegesis. These are sounds that your characters can hear, e.g., dialogue, footsteps, or a ringing phone. Diegetic sound, when it is incorporated into a scene, helps put the audience into the setting of the story. It assists you in expressing reality and interaction between characters. You employ it to make the experience seem more real, and the audience can sense that they are there with the characters and are living through the events happening in the story world

Types of diegetic music

• Dialogue

Dialogue is a conversation between characters and moves the story along. Naturalistic or stylized dialogue will help you produce various tones. Pitch, accents, and subtext are used to communicate character feelings and intentions. These details are important to listen to, as knowing them will make dialogue seem natural and interesting.

• Environmental and ambient sounds

Background sounds such as wind, traffic, crowds, and nature are considered ambient sounds. These sounds can be used to create time, place, and mood. The correct overlay of the environmental sound provides a realistic, immersive environment that supports the context of the narrative and immerses the audience in the scene.

• Sound effects within the story world

The use of sound effects like footsteps, doors, weapons, and machinery makes the story sound like a real one. You may select realistic recordings or computer-generated sounds, and they may be augmented with Foley artistry. Considerate sound design makes each action heard, which helps to be immersive and clear in the story.

• Music as diegetic sound

Diegetic music has its origins in the narrative, such as radios, live bands, or singing characters. You may take advantage of it to emphasize plot highlights and add emotional appeal. On-screen music interacts naturally with characters, supporting narrative events and providing a stronger engagement of the audience.

Functions of diegetic sound

• Enhancing realism and immersion: Diegetic sound makes the story world feel authentic. You perceive actions, environments, and events, increasing your sense of presence within the scene.
• Providing narrative information: Diegetic audio conveys essential plot details. You detect dialogue, alarms, or environmental sounds, helping you understand events and character intentions clearly.
• Establishing spatial awareness: Diegetic audio helps you sense where objects and characters exist. You can detect distance, direction, and location of sound sources, enhancing your spatial understanding of the scene.
• Supporting character development: Diegetic sound expresses emotions and traits. You hear footsteps, breathing, or laughter, revealing personality and feelings beyond what visuals alone can show.
• Reinforcing continuity and coherence: Diegetic cues maintain flow between shots. You perceive sound connections across actions and environments, keeping the story logical and consistent.
• Helping audiences orient themselves within the story world: Diegetic audio guides your focus and navigation. You locate movements, events, and spaces naturally, preventing confusion within the story world.

What is non-diegetic sound

Non-diegetic sound is any sound that is not part of the story world. These are the sounds that are not audible to your characters but are audible to your audience. Background music, narration, or dramatic stings can be examples. You apply non-diegetic sound to inform the viewers about their emotions and to focus on the narrative elements. It assists you in forming mood, tension, and pacing, and provides an extra layer of meaning to what is visible on the screen.

Types of non-diegetic sound

• Background music/film score

Background music consists of orchestral, electronic, minimalist, or thematic music. You may use leitmotifs or themes of character to give a cue to identity or emotion. Adequately stratified, music directs the audience to their emotions, highlights the dramatic scenes, and regulates the speed of the narrative. It can assist you in emphasizing plot progression and establishing the emotional tone of the story.

• Narration and voice-over

Narration is either omniscient narration or character voice-over. Voice-over can be used to give perspective, insight, or reliability. It provides exposition, interior monologue, or backstory that is not conveyed by characters. Narration is a tactic that provides clarity and strength to what you want to say.

• Non-diegetic sound effects

These are dramatic stings, whooshes, and hits. Exaggerated or symbolic sounds may be used to accent action or emotion. They are commonly found in genre movies such as horror, action, or comedy. Tension, surprise, or comedy time is aided by proper application.

Functions of non-diegetic sound

• Guiding emotional responses: Non-diegetic sound influences viewers' feelings. You can evoke fear, joy, sadness, or suspense using music, stings, or voiceover.
• Providing subtext and thematic meaning: Audio adds hidden meaning. You can highlight symbolism, reinforce themes, or foreshadow events without visual cues.
• Enhancing pacing and rhythm: Music and sound cues help control narrative speed. You can accelerate action or provide reflective pauses for effect.
• Foreshadowing and dramatic irony: Sound hints at future events. You can create anticipation, tension, or awareness beyond what characters know.
• Creating tension, suspense, or relief: Non-diegetic elements manipulate your emotional experience. You feel suspense build or tension release at critical moments.
• Reinforcing genre conventions: Audio signals genre expectations. You can use stings, motifs, and cues familiar to horror, action, or comedy audiences.

Diegetic and non-diegetic sound: Key differences

Diegetic non-diegetic sounds play different functions in the storytelling. Diegetic sound is created in the story world, allowing you to hear what the characters hear. Non-diegetic sound is beyond that world, telling your emotional reaction through music or narration. You interpret them differently: diegetic makes it more true to life, and non-diegetic makes it more mood and tension. Knowing diegetic and nondiegetic music strengths and weaknesses will aid you in creating scenes that can attract audiences. Diegetic is more immersive, non-diegetic is more emotional, and a combination of the two will have the greatest effect on the narrative.
